Driving multi-lane roundabouts

In a multi-lane roundabout, you will see two signs as you approach the intersection: The yellow "roundabout ahead" sign and a black-and-white "lane choice" sign. You will need to choose a lane prior to entering the roundabout.

You choose your lane in a multi-lane roundabout the same way you would in a traditional multi-lane intersection. To go straight or right, get in the right lane. To go straight or left, get in the left lane. Drivers can also make U-turns from the left lane.

The graphics below show what turns can be made in multi-lane roundabouts. The arrows in yellow show the movements that can be made from the right lane, and the arrows in green show the movements that can be made from the left lane.

Once you have selected your lane, watch for pedestrians in the crosswalk as you approach the roundabout.

At the dashed yield line, look to your left and yield to drivers already in the roundabout. Remember, in a multi-lane roundabout, you must yield to both lanes of traffic.

Once a gap in traffic appears, merge into the roundabout and proceed to your exit. Look for pedestrians and use your turn signal before you exit. If there is no traffic in the roundabout, you may enter without yielding.

Trucks/oversize vehicles and roundabouts

Roundabouts are designed to accommodate vehicles of all sizes, including emergency vehicles, buses, farm equipment and semitrucks with trailers. Oversize vehicles and vehicles with trailers may straddle both lanes while driving through a roundabout.

Many roundabouts are also designed with a truck apron, a raised section of pavement around the central island that acts as an extra lane for large vehicles. The back wheels of the oversize vehicle can ride up on the truck apron so the truck can easily complete the turn, while the raised portion of concrete discourages use by smaller vehicles.

Because large vehicles may need extra room to complete their turn in a roundabout, drivers should remember never to drive next to large vehicles in a roundabout.
